Basic Concepts in CDISC SDTM
Observations and Variables
• The SDTM provides a general framework for describing the
organization of information collected during human and animal
studies.
• The model is built around the concept of observations, which
consist of discrete pieces of information collected during a study.
Observations normally correspond to rows in a dataset.
• Each observation can be described by a series of named
variables. Each variable, which normally corresponds to a
column in a dataset, can be classified according to its Role.
• Observations are reported in a series of domains, usually
corresponding to data that were collected together. A domain is
defined as a collection of observations with a topic-specific
commonality about a subject.
